Bummer. It was a great course and, as you mentioned, great fun.
I remember the “notorious” W pattern. We had taken time off for lunch and since our instructors hadn’t returned yet and we had cones layed out and old police Kawasaki’s at hand, we thought we’d have a go at the W. I aced it first time through and spent the rest of lunch riding through it, both directions, until our instructors finally came back and scolded us for riding while they weren’t there. Again, great fun.
